FAYETTEVILLE, Ga. (AP) -- WWE wrestler Chris Benoit, his wife and son were found dead Monday and police said they were investigating the deaths as a homicide.

Lt. Tommy Pope of the Fayette County Sheriff's Department said the three were found at their home about 2:30 p.m., but refused to release details.

Pope said results of autopsies on Benoit, his wife Nancy, and 7-year-old son Daniel were expected Tuesday.

Benoit, 40, was a former world heavyweight champion, Intercontinental champion and held several tag-team titles over his career.

"WWE extends its sincerest thoughts and prayers to the Benoit family's relatives and loved ones in this time of tragedy," the federation said in a statement on its Web site.

Benoit was scheduled to perform at the "Vengeance" pay-per-view event Sunday night in Houston, but was replaced at the last minute because of what announcer Jim Ross called "personal reasons."

Benoit, a Canadian native, maintained a home in metro Atlanta from the time he wrestled for the defunct World Championship Wrestling.

The WWE canceled its live "Monday Night RAW" card in Corpus Christi, Texas, and USA Network aired a three-hour tribute to Benoit in place of the scheduled wrestling telecast.
